This whole comment basically says, "it is how it is, so you can't criticize it." It is like saying, "racism will exist. Humans are just racist. Should businesses be publicly shamed for being racist if it is what their users want?"

Now as for how we should treat businesses that treat people better based on their looks is not something I have a strong opinion about, but my two cents is that looks should not be a factor of how people get treated because it is possible that representation of "ugly" people in media could make many diverse looking people "attractive" to younger generations. This would be beneficial because it means that talent would have more priority over looks than before.
